NON-REFILLABLE BOTTLE SPECIFICATION forming part of Letters Patent No. 792,170, dated June 13, 1905. l Application filed August l5, 1904. Serial No. 220,725.

To all whom t may concern:

Be it known that I, JOHN SHERMAN ROOT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following, taken in connection with the drawings, is a specification.

My invention has for its object the produc- -tion of a device for preventing the refilling of bottles after they have once been emptied, and from the following description it will be seen that I have provided an arrangement which is exceedingly simple and cheap in construction and very effective in operation. The inside of the neck of a bottle in which this device is to be used is a perfect cylinder. The device is adapted to lit it snugly and is passed down the neck of the bottle to the shoulder after the bottle is lled. There is no additional expense in the manufacture of the bottle itself. Any experienced workman can easily and readily make the inside diameter of the bottle the required size and leave the diameter at the shoulder slightly less than at the top for the space of a fraction of an inch.

I have illustrated the device in preferred form in the accompanying drawings, in Which- Figure l is a central vertical section of a bottle with my invention applied thereto. Fig. 2 is a similar section showing the action of the valves when the bottle is tipped. Fig. 3 is a central vertical section through the cylinder and device applied therein. Figs. 4 and 5 are details of the valves. Fig. 6 is a detail of the middle section having a modied form of hinge. Fig. 7 is a plan view of the top section, and Fig. 8 is a modified form of valve.

In carrying out my invention I employ a cylinder A,preferably made of aluminium, but which might be made of any other material suitable for the purpose. This cylinder A is to be made of a size to permit its being placed inside the neck of a bottle and adjusted therein after the bottle has been lled. Inside of this cylinder A, I have arranged my device for preventing the refilling of the bottle. This device is also preferably made of aluminium and is cut from a single piece of material and bent to form three sections-the top section B,

the middle or diagonal section C, and the bottom section D. The top and bottom sections B and D are made circular to fit Within the cylinder A and are joined together at diametric-ally opposite points o and o.

The top section B is provided with a number of perforations E, Fig. 7, near its circumferential edge upon the side opposite to its point of connection with the middle or diagonal section C. The middle section C is provided with an-aperture c near its point of connection with the top section. The valve (Z is hinged or pivotally secured to this middle section at a point Which will permit it to be closed over the aperture c. This valve is disk-shaped, as shown in Fig. 5, and has an aperture c/ through the center thereof. A small cork c2 is passed through the aperture c', which gives the valve more buoyancy than that of its own weight. A small projection d is provided upon the edge of this valve to keep it from coming in contact with the top section B. The bottom section D is also provided with an aperture e, and pivotally secured to this section at a point which will permit it to close over the aperture c is another valve e. The construction of this valve is similar to the one just described, with the exception that it has a projection e2 secured near the hinge.

In the top section near its point of attachment to the middle section is a needle-point opening c3, Fig. 7 which affords a vent when the liquid is being poured from the bottle. The small openings g g around the hinges of the other two sections C and D perform the same function when liquid is being poured from the bottle.

In emptying' the liquid from the bottle the pressure thereof immediately raises the valves and permits it to pass therethrough and out through the apertures Ein the top section. If an attempt should be made to refill the bottle, the pressure of the liquid upon the valve would close it over the aperture and prevent its passing beyond the middle section. The opening in the middle section being located at such an acute angle from the apertures E in the top section, it would be absolutely irnpossible by the insertion of a Wire or other instrument to reach this valve without breaking the top section from the middle section,

which at once indicates that the bottle has been refilled or an attempt has been made to do so. In Fig. 6 I have shown a simplified form of hinge which might be employed in securing' the valves to either this section or section D. In this form the metal at each side of the aperture is raised sufliciently to enable a Wire c" to be inserted therethrough to form the hinge. The operation of the valves would be the same as that shown in Figs. l and 2.

In Fig. 8 I have shown a modified form of valve comprising two sections f f, being slightly depressed at the center to make them cup-shaped. They are adapted to swing upon a pivot f2, passed laterally therethrough and to open and close the apertures in either of the sections C; and D.

While I have described in detail the preferred form of my construction, I do not desire to be limited to the exact construction shown, as some of the details may be changed Without departing from the spirit of my invention, which consists, essentially, in providing a device of this kind which shall be so simple in its construction as to permit of its commercial utility, as well as being effective for the purpose set forth. The construction of the valves might be changed and the cork omitted. The projections on each of these valves might be omitted. The valve e in the bottom section could as effectively be placed near the point of connection between the bottom and middle sections. Other changes in the details might be made, and I contemplate any which might be considered equivalent constructions.

I claimg l. In a device of the class described, the

combination with a cylinder, top, bottom and diagonal sections disposed therein, thetop section having perforations near the circumferential edge thereof, the diagonal and bottom sections each having an aperture therein, valves secured to said sections and adapted to close over said apertures to prevent relilling the bottle substantially as described.

2. In a device of the class described the combination of a cylinder adapted to be placed Within the neck of a bottle, top, bottom and middle sections disposed Within said cylinder, said top and bottom sections being parallel with each other and connected together at opposite points by the middle section, said top section being perforated and said middle and bottom sections having valve-openings therethrough, and valves adapted to open and close over said openings substantially as described.

3. In a device of the class described, the combination of a cylinder adapted to lit within the neck of a bottle, top and bottom sections closing the ends of said cylinder, a middle section diagonally joining the top and bottom sections, said top section having perforations near the circumferential edge thereof, an aperture in the diagonal section near its point of connection with the top section, an aperture in the bottom section opposite its point of connection With the middle section, valves secured to said middle and bottom sec* tions and adapted to close the aforesaid apertures against the refilling of the bottle, substantially as described.
